The Kepler scientific workflow system provides domain scientists with an easy-to-use yet powerful system for capturing scientific workflows (SWFs), a formalization of the ad-hoc process that a scientist may go through to get from raw data to publishable results.
XML-based information mediation with MIX
- C. Baru, Amarnath Gupta, Vincent Chu
- Computer ScienceACM SIGMOD Conference
- 1 June 1999
The MIX mediator system, MIX, uses XML as the common model for data exchange and employs XML DTDs as a structural description (in effect, a “schema”) of the exchanged data to facilitate user-friendly query formulation and for optimization purposes.
An Ontology-Driven Framework for Data Transformation in Scientific Workflows
- S. Bowers, Bertram Ludäscher

- 25 March 2004
This paper defines a generic framework for transforming heterogeneous data within scientific workflows, which relies on a formalized ontology, which serves as a simple, unstructured global schema.

Special Issue: The First Provenance Challenge
- L. Moreau, Bertram Ludäscher, Yong Zhao
- Computer ScienceConcurrency and Computation
- 1 April 2008
A functional magnetic resonance imaging workflow was defined, which participants had to either simulate or run in order to produce some provenance representation, from which a set of identified queries had to be implemented and executed.
Scientific Workflows: Business as Usual?
- Bertram Ludäscher, M. Weske, T. McPhillips, S. Bowers
- Computer ScienceInternational Conference on Business Process…
- 27 August 2009
An introduction and overview of scientific workflows is provided, highlighting features and important concepts commonly found in scientific workflow applications and proposing a number of research opportunities for cross-fertilization between the scientific workflow and business workflow communities.
Actor-Oriented Design of Scientific Workflows
- S. Bowers, Bertram Ludäscher
- Computer ScienceInternational Conference on Conceptual Modeling
- 24 October 2005
This work develops a formal model for scientific workflows based on an actor-oriented modeling and design approach, originally developed for studying models of complex concurrent systems, and extends this framework by introducing a novel hybrid type system.
The Open Provenance Model (v1.01)
- L. Moreau, Beth Plale, Paul T. Groth
- Computer Science
- 17 July 2008
The Open Provenance Model is introduced, a model for provenance that is designed to meet the following requirements: to allow provenance information to be exchanged between systems, by means of a compatibility layer based on a shared provenance model.
